Reference range
CD19+ B-cells with kappa light chain restriction are interpreted in the context of total B-cell count and kappa/lambda ratio. Normal kappa/lambda ratio is approximately 0.5-2.0 in polyclonal B-cell populations. Reference ranges vary by laboratory; results should be interpreted alongside total CD19+ B-cell count.N/A
No special patient preparation required. Recent corticosteroid therapy, chemotherapy, or immunosuppressive medications may affect B-cell counts and should be documented.
Clinical interpretation
